New Review Mass Changes in Chemical Reactions—Microscale Chemistry
What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine differences in mass.

Chemistry Concepts: Conservation of Mass
There is no narration in this video, just footage of a hand performing a chemical reaction set to magic-show-style music. Starting mass is shown in text. Solutions are mixed so that a precipitate forms, and then ending mass is shown....
